firstly, I haven't really used the 3D option on my Samsung TV before, but thought I'd give it a try on my Windows 7 Media Center PC with the 3D Olympics coverage here in Australia.
3D mode works, but the problem is that I get a nasty offset, ie I can see text multiple times and slightly offset to the right (like a drop shadow).
This is after I went out and bought a new graphics card (AMD HD6450) that's specifically HDMI 1.4a compatible and also a new HDMI 1.4a cable.
I get the same problem when trying to watch 3d content through Youtube, however watching the 3D signal directly on the LCD, ie without using the PC, works perfectly, no offset or ghosting.
The LCD is connected to the Media Center PC via HDMI, display settings in both Windows 7 desktop settings and Media Center itself are set to 1080p, 50Hz, I also tried other resolutions and refresh rates, which didn't help.
I also tried GPU scaling and over/underscan, which didn't solve the problem.
The motherboard is fairly old (Asus M2N-PV VM), but I wouldn't think that this could cause the issue?
Any ideas how to get rid of the offset?
